The first hot air balloon flight

The Marquis d’Arlandes, a friend of the Montgolfier brothers, wishes to attempt the first hot air balloon flight.

However, King Louis XVI does not authorize the flight. A clever strategist, the Marquis makes another attempt.

This time, the King agrees—but on one condition: the Marquis must prove his worth by completing a series of challenges in Anneyron!

Help him rise to the occasion and achieve the first hot air balloon flight.

Practical information:

• The route is approximately 2 kilometers long and takes about 1.5 hours
• Departure point: the parking area south of the Anneyron pond
• Make sure your device is well charged before starting
• At each stage, clues will guide you along the way—read them all carefully
• If you’re unable to complete a challenge, you can skip it using the red padlock at the bottom right
